PRODUCT OVERVIEW
The DigiTrace ECW-GF electronic controller provides
accurate temperature control with integrated 30-mA
ground-fault protection. The ECW-GF is ideal for pipe freeze
protection, flow maintenance, freezer frost heave, floor
heating and snow melting applications.
The ECW-GF is housed in a NEMA 4X enclosure designed to
be wall mounted or installed on a pipe with the optional Raychem FTC-PSK pipe stand kit.
The controller includes a window and a digital display that
shows the measured temperature, set point temperature
and alarm conditions (temperature sensor failure, high or
low temperature and ground-fault) if detected.
Alarm conditions can be indicated via a Form C dry contact
connected to a building management system. Status LEDs
indicate whether the digital display is showing the set point
or actual temperature or if the controller is in an alarm
state.
The ECW-GF can be programmed to maintain temperatures
up to 200°F (93°C), at voltages from 100 to 277 V, and is
capable of switching current up to 30 amperes.

ECW-GF using a separate junction box
Programming the set point temperature, deadband, and the
high and low alarm thresholds on the controllers is accomplished using the built-in digital display and push buttons. A
9-V battery connector is supplied to allow programming the
controller before the heating cable circuit power is provided.
An optional remote display panel, the DigiTrace ECW-GF-DP,
is available. This remote display provides remote alarm
indication and ground-fault test and reset capability. The
ECW-GF-DP can be installed indoors in a standard duplex
box located up to 328 ft (100 m) from the controller.
The ECW-GF is supplied with a 25-foot thermistor for line,
slab or ambient sensing temperature control.
